Method of manufacturing friction plates.

摘要

A friction plate in the shape of a disc is used in a clutch device to transfer a rotational torque from a driving member to a driven member and has frictional thin films on its side surface. These films are formed by spraying particulate materials on the side surfaces of the friction plate. According to the present invention the thin films are compressed by a compression roller arranged on the way of a path for feeding the metal strip having the thin film on its side surfaces.
